It’s one thing to announce new refrigerants. It is another thing to figure out how they will work in real-life situations. With the industry facing an apparent shift to low global warming potential (GWP) refrigerants, the performance of those gases is being carefully studied.
At the most recent 15th International Refrigeration and Air Conditioning Conference at Purdue University (one of three concurrent conferences, the others dealing with compressors and high performance buildings), a number of researchers presented papers as part of an “Alternative Refrigerant Performance Comparisons” program.
